Yes and mongoloids consider $13 million in settlements to be blood money paid to the libtard, socialist, sexually deviant, foetus murdering socialist mafia.

^You seem to be launching from the wrong platform. Do you have a clue who you really are?

Poor guy is just going to retire in disgrace with his millions of dollars while he lives out his golden years and pays hookers to let him call them his wife while he throws them down the stairs and shoves falafel up his ass.

Yawn. They only fired him once it started hurting their advertising dollars. And they sent him packing with a generous payout. Not much of a victory.

Apparently the sexual harassment scandal was potentially queering the second run at Sky in England (Europe?) that News Corp was attempting. The first attempt was scuttled by the Rebekah Brooks phone hacking shenanigans.

It is easier to drop a 67 y/o whose demographics are 75 to dead and replace him with much cheaper talent and keep your global deals on track. Maybe they can get out of the gold/silver coin, reverse mortgage and lubricated catheter business and attract better advertisers with a younger, more appealing host.

They've been grooming Tucker Carlson for that spot for a while. I assume he's about Stephen Colbert's age. Maybe a little younger.
